Abstract
Disclosed is a diaphragm-type sea water pump. The diaphragm-type sea water pump comprises a machine frame. A motor, a speed reduction box, a diaphragm water pumping mechanism are installed on the machine frame. Sea water and driving mechanical components are separated by diaphragms of the diaphragm-type sea water pump, meanwhile, a gap between a front housing and a rear housing is sealed, and the sealing effect is good. Meanwhile, corrosion, caused by sea water, on water pump moving components is avoided, and the service life of the water pump is prolonged. In addition, the water pump does not need to conduct water injection, the limitation of use conditions does not exist, the sealing effect of the position of the connecting opening of a water guiding pipe and an opening-and-closing cavity in the process of water pumping is strengthened due to a rubber layer covering the surface of a sealing ball, and the water pumping performance is improved.

The model utility content
The utility model is for the water pump that carries out at present seawater and extract, easy to wear and corrosion, and aging speed is fast, easily leaks, and the problems such as damage motor, designed a kind of diaphragm type sea water pump.
diaphragm type sea water pump of the present utility model, comprise frame, motor is installed on frame, speed reducer, the barrier film water pumping mechanism, motor drives speed reducer, on the output shaft of speed reducer setting, eccentric wheel is installed, be set with a rocking arm on eccentric wheel, the barrier film water pumping mechanism comprises the aqueduct of vertical setting, front end-cover and the rear casing relatively installed, between front end-cover and rear casing, barrier film is installed, the rear casing rear end is provided with conduit, be slidably fitted with piston rod in conduit, the front end of conduit is connected with diaphragm center, the rear end of conduit and the front end of rocking arm are hinged, the front portion of front end-cover is communicated with the middle part of aqueduct, the top of aqueduct, bottom is respectively arranged with water outlet, water inlet, the upper and lower of aqueduct all is provided with the logical chamber of closing, logical closing in chamber all is equipped with a ball sealer, the logical top of closing chamber all is equipped with the baffle plate that is provided with through hole.
Preferably, the surface coverage of ball sealer has rubber layer.
Preferably, the diameter of ball sealer is greater than the twice of aqueduct internal diameter.
Preferably, the logical twice of the internal diameter in chamber greater than the ball sealer diameter of closing.
The beneficial effects of the utility model are: the barrier film of diaphragm type sea water pump separates seawater and the mechanical part of transmission, simultaneously with the gap sealing between front end-cover and rear casing, good sealing effect, avoided simultaneously the corrosion of seawater for the water pump moving element, extended the working life of water pump, and water pump does not need water, restriction without service condition, the rubber layer that covers the ball sealer surface has strengthened aqueduct and the logical sealing effect that closes the connection mouth place in chamber in the pump process, has improved the performance of drawing water.
Description of drawings
Accompanying drawing 1 is the partial sectional view of diaphragm type sea water pump;
Embodiment
Diaphragm type sea water pump of the present utility model, as shown in Figure 1, comprise frame 1, and motor 2, speed reducer 3, barrier film water pumping mechanism 4 are installed on frame 1.Motor 2 drives speed reducer 3, on the output shaft 5 that speed reducer 3 arranges, eccentric wheel 6 is installed, and is set with a rocking arm 7 on eccentric wheel 6.
barrier film water pumping mechanism 4 comprises the aqueduct 8 of vertical setting, front end-cover 9 and the rear casing 10 relatively installed, between front end-cover 9 and rear casing 10, barrier film 11 is installed, rear casing 10 rear ends are provided with conduit 12, be slidably fitted with piston rod 13 in conduit 12, the front end of conduit 12 is connected with barrier film 11 centers, the front end of the rear end of conduit 12 and rocking arm 7 is hinged, the front portion of front end-cover 9 is communicated with the middle part of aqueduct 8, the top of aqueduct 8, bottom is respectively arranged with water outlet 14, water inlet 15, the upper and lower of aqueduct 8 all is provided with the logical chamber 16 of closing, logical closing in chamber 16 all is equipped with a ball sealer 17, the logical top of closing chamber 16 all is equipped with the baffle plate 18 that is provided with through hole.
The surface coverage of ball sealer 17 has rubber layer, and the diameter of ball sealer 17, greater than the twice of aqueduct 8 internal diameters, leads to and closes the twice of the internal diameter in chamber 16 greater than ball sealer 17 diameters.
During original state, two ball sealers 17 are due to gravity, all drop on logical closing on 16 bottoms, chamber and opening that aqueduct 8 is connected.
During work, motor 2 drives eccentric wheel 6 by speed reducer 3, makes eccentric wheel 6 drive piston rod 13 in the interior to-and-fro motion of conduit 12 by rocking arm 7, and the water pipe that is connected to water inlet 15 stretches in seawater.
Piston rod 13 pulls barrier film, and the pressure in front end-cover 9 increases, and the ball sealer 17 on top is subject to outside inside pressure and the gravity of self, is pressed on logical closing on the opening of 16 bottoms, chamber,, with the opening sealing, makes and logically closes chamber 16 and be in closed condition; The outside inside pressure that the ball sealer 17 of bottom is subject to overcomes the gravity of himself, ball sealer 17 is removed from the logical opening that closes 16 bottoms, chamber, opening is opened, make and logical close chamber 16 and be in open mode, seawater is subject to outside inside pressure, closes chamber 16 along water inlet 15, aqueduct 8, bottom logical successively and enters in the water containing chamber body that front end-cover 9 and aqueduct 8 middle parts form.
